What is EN ISO 9972:2018?

Introduction

EN ISO 9972:2018 is a technical standard that provides guidelines for determining the energy performance of buildings by conducting measurements. It focuses on the measurement of air permeability, also known as air leakage, in residential and commercial buildings. This article delves into the details of EN ISO 9972:2018 and its importance in evaluating the energy efficiency of buildings.

Understanding EN ISO 9972:2018

The standard outlines the procedures for measuring air permeability using a blower door test. Air permeability measures the amount of air that escapes or enters a building through cracks, gaps, seams, and other unintentional openings. By measuring air leakage, it becomes possible to identify areas where energy loss occurs and take appropriate steps to improve the energy efficiency of a building.

EN ISO 9972:2018 covers various aspects of conducting the blower door test, including equipment requirements, test procedures, calculation methods, and reporting of results. The standard offers essential guidance to professionals involved in energy audits, energy performance assessments, and building energy certifications.

Importance of EN ISO 9972:2018

EN ISO 9972:2018 plays a crucial role in promoting energy efficiency in buildings. It helps identify areas of concern in terms of air tightness and allows for targeted improvements to reduce energy waste. By reducing air leakage, buildings can maintain comfortable indoor environments, decrease heating and cooling loads, save energy, and lower greenhouse gas emissions.

Moreover, compliance with this standard is often a requirement for building certifications and energy labels. It enables building owners to demonstrate their commitment to sustainable practices and provides transparency to potential buyers or tenants regarding the energy performance of a building.

Conclusion

EN ISO 9972:2018 is an important technical standard that focuses on measuring air permeability in buildings. By conducting the blower door test and following the guidelines outlined in this standard, professionals can accurately assess the energy efficiency of residential and commercial buildings. Compliance with EN ISO 9972:2018 helps to identify areas for improvement, reduce energy waste, and promote sustainable practices in the construction industry.
